Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540148, here are decompositions:

29 + 540119 = 540148
47 + 540101 = 540148
107 + 540041 = 540148
227 + 539921 = 540148
251 + 539897 = 540148
311 + 539837 = 540148
419 + 539729 = 540148
461 + 539687 = 540148

Showing the first eight; more decompositions exist.
